Question

Ratio of vegetative cells in the male and female gametophytes of an angiosperm plant respectively is

• A. $3:\alpha$
• B. $2:3$
• C. $1:3$
• D. $3:1$

Answer 1

The correct option is C $1:3$

Angiosperms have both female and male gametophytes. They are composed of few cells and are embedded within the sexual organs of the flower. The female gametophyte develops within the ovule and generally consists of 3 vegetative cells (three antipodal cells, one central cell, two synergid cells) and one egg cell. The female gametophyte is also commonly called the embryo sac or megagametophyte. The male gametophyte, also called the pollen grain or microgametophyte, develops within the anther and consists of two sperm cells encased within a vegetative cell. Therefore the ratio of vegetative cells in the male and female gametophytes of an angiosperm plant respectively is 1:3.
